As of July 2016, Crowley was ranked as the 13th largest private company in Florida, employing approximately 5,300 people worldwide with revenues of $2.2 billion.

[8] In addition to acquiring larger vessels, the company expanded in the 1920s into Los Angeles Harbor with tugboats for ship assists and into Puget Sound with tug and barge transportation.

This led to Crowley’s Alaska common carrier services whereby railcar, breakbulk, containerized and bulk petroleum cargoes were delivered to more than 130 villages, many of which lacked docking facilities.

Beginning in 1968, utilizing the earlier pioneering experience in the Arctic, Crowley began summer sealifts of equipment, supplies, buildings and production modules to Prudhoe Bay.

The Exxon Valdez oil spill was the second largest in U.S. history (after Deepwater Horizon, 2010) and Crowley was the prime supplier of marine equipment and personnel for the cleanup.

To try to avoid future disasters, the Alyeska Pipeline Service Company contracted with Crowley to provide tanker assistance and escort work in Valdez and Prince William Sound using tugs with “best available technology.” In mid-1994, the top leadership of the corporation changed for only the second time in more than 100 years.

In January 2010, Crowley Liner Services reached an undisclosed settlement with plaintiffs (shippers) who had alleged violations of United States and Puerto Rican antitrust laws.

The company publicly denied violating the antitrust laws but said it wanted to be rid of the high cost and burden of litigation, which they expected to continue for several more years.

[9][10] Crowley and its employees then donated $80,000 to the American Red Cross in support of Haiti relief efforts[11] and transported an estimated 15,000 emergency housing units to the island.

In Dec. 2010, Crowley's Alaska fuel sales and distribution enterprise added eight Shell Oil service stations to its wholesale network.
